TSR-3, 3Amps from a small brick

Have you ever searched for a reliable, high efficiency step down regulator with Vin up to 30VDC? TSR-3 series from TRACOPOWER solves this problem.

This is an archive article published 01/14/2016. Some information may no longer be up to date and in line with the current state. Please contact us in case of interest.
The TSR 3 models are non isolated step down switching regulators. Negative output voltage models are also available.

They come in a tiny open frame package of 15.5 x 9.4 x 6.2mm. The high efficiency of up to 95% admits a full load operation up to 50°C and up to 85°C with 50% current reduction. A low standby current, a very wide input range and no requirement for heatsink give these switching regulators a significant advantage over linear regulators while these regulators require only a portion of the area of linear regulators (with heatsink). But the wide input voltage range is probably the most important feature of TSR 3 family.

Together with a remote On/Off input and protection against short circuit and over temperature the TSR 3 Series models are ideal point of load regulators for high reliable and energy critical applications such as telecom, medical, industrial and battery powered applications.
